Greek coin ID [решено]

Hi,
A friend of mine asked if I could find some info on this coin. He says it looks like the coin is painted on and the paint is flaking. So I assume it is a fake. What do you think? (sorry don't have better photos). Around 30mm and 20g.


Thank you

It says "Sotiros Irakleous" and at bottom it says "Thasion".
Can't say it's authentic or not.

The legend is correct for this coin as a tetradrachm from Thasos, Thrace. The monogram in the left field is 'M'.

However, the weight of a tetradrachm should be in the area of 16 grams. Yours at 20 grams is a copy. The flaking paint is also a good indication that it is a copy. It is a popular coin that has been copied from ancient to modern times.

A variety of examples can be seen here:

Thank you very much.
